Bug#502623: grub-pc: device name change needs to be mentioned in README or README.Debian

[Osamu Aoki]

Package: grub-pc
Version: 1.96+20080724-10
Severity: normal

I think current README is too weak to mention device name change from
GRUB legacy to GRUB 2.  This is causing bugs by d-i developer as
documented in:
 http://bugs.debian.org/502446

This is documented in http://grub.enbug.org/grub.cfg as
---
NOTE: you can use the update-grub utility to generate a grub.cfg file
for you

GRUB 2 uses new bashish scripting language that is used to build menus.
At startup file grub.cfg will be read and executed.

Please note that partition numbering has been changed to start from 1
(in grub legacy it started from 0).

Please add short description of this change in README or add
README.Debian such as:
